Fractional–Rational Calibration for Laser-Induced Breakdown Spectroscopy (LIBS) Analysis of Steels with High Matrix Variability
Read more: https://doi.org/10.1177/00037028261456320
#SAS #Spectroscopy #LIBS #Calibration #steel

Abstract: The results of an original calibration methodology that accounts for interelement influences in the analysis of alloyed steels using laser-induced breakdown spectroscopy (LIBS) are presented. The results were obtained from a dataset of spectra provided for the regression competition at the LIBS 2022 conference and available online. The dataset includes spectra from 41 steel samples with known concentrations of major alloying elements (chromium, nickel, manganese, molybdenum, carbon, silicon, copper) and 15 samples with unknown compositions for model validation. The concentration of alloying elements varies over a wide range, with iron content ranging from 98% to 41%. To reduce spectral line position instability, we applied a preprocessing method that maximizes the correlation of each spectrum with the first spectrum in the dataset. The implementation of the developed calibration methodology led to an improvement in the root mean square error of the analysis, with reduction factors ranging from two (for nickel and molybdenum) to five (for manganese and chromium) when compared to classical calibration.

Raman Spectroscopy of Biofluids: Fusion Strategies for Detecting Oral Potentially Malignant Disorders and Oral Cancers

#SAS #Spectroscopy #Raman #Oral #Malignant #Cancer #Biofluids

Abstract: Minimally invasive screening tools are essential for early detection of oral cancers to reduce mortality. A key necessity is the ability to differentiate highly heterogeneous oral potentially malignant disorders (OPMDs) and cancers. This study evaluated serum and salivary Raman spectroscopy (RS) for detecting OPMDs and oral cancers. Blood and saliva were collected from 13 non-habitual controls (NHC), 13 tobacco habitués (HC), 10 leukoplakia (L), 25 oral submucous fibrosis (OSMF), and 14 oral squamous cell carcinoma (OSCC) subjects. Raman spectra were acquired, pre-processed, and analyzed using multivariate methods. Serum outperformed saliva in individual classification models, achieving accuracies of 92%, 85%, 100%, 88%, and 85% for NHC, HC, L, OSMF, and OSCC, respectively. Saliva, despite its non-invasive advantage, showed higher misclassification among HC, L, OSMF, and OSCC. Low-level fusion of serum and saliva spectral data improved the classification of OSMF, OSCC, and NHC groups compared to saliva models. Mid-level fusion surpassed both biofluids, reaching 100% accuracy for NHC, L, and OSMF. Multivariate curve resolution–alternating least squares analysis of serum revealed altered protein- and lipid-related features among groups. These findings demonstrate the potential of serum and salivary RS, particularly with data fusion, as effective tools for OPMD and oral cancer screening.

Real-Time Quantification of #Hydrogen and #Deuterium Using Laser-Induced Breakdown Spectroscopy (#LIBS) in the Off-Gas of an Engineering-Scale Pumped Molten Salt Loop
Read more: https://doi.org/10.1177/00037028261454365
#SAS #Spectroscopy #molten #salt

Abstract: Laser-induced breakdown spectroscopy (LIBS) is being considered for elemental analysis of radionuclides transported into the off-gas system of molten salt reactors. A mobile LIBS system was calibrated for gas-phase measurements of hydrogen (i.e., protium, denoted here as H) and deuterium (D) in argon (Ar). The system was then used to quantify the concentrations of H and D in the off-gas of an engineering-scale molten salt loop (∼200 kg salt) following the addition of H2 or D2 as a 4% blend in Ar. The limits of detection for H and D were determined to be 0.0013 and 0.0011 mol% (13 and 11 parts per million), respectively. This research was carried out at the U.S. Department of Energy’s Oak Ridge National Laboratory in the Facility to Alleviate Salt Technology Risks (FASTR) pumped salt loop. Previous molten salt LIBS research has predominantly been performed at the bench scale, thus this study represents a major stride toward deploying LIBS technology for monitoring the performance of molten salt reactors. During the FASTR testing, the LIBS system operated continuously for several days. This online monitoring campaign demonstrates advancement in the application of LIBS for online monitoring of off-gas in molten salt systems.
